THIS is what i'm talking about. Let those brushes breathe in the space, place them in with confidence and power, use them to sculpt the shape in light and shadow. Think it all out as sculpting, you use light and dark to create volumes and shapes in space. You've taken a bold step ahead and i congratulate you for it. Keep working in this bold no-stress manner, you'll find yourself learning faster than before. I also think that for this particular type of image and attitude the technique fits and helps deliver the message. Rock on, I'm happy to see this!
